In the midst of preseason teardown/buildup and wondering what is the general take on wheel bearings and how long they last and when they should be replaced? With 6+ full race seasons (plus 8-10k of miles before this bike became a race bike) on them I'm just wondering when they should be replaced? They are on a 2001 F4i.

And rybo posted up before i could even edit, which was to add that there are no signs right now that they are bad at all...smooth and quiet rolling with no play or sticking at all.
